So I came up with an idea that you could buy slayer tasks for slayer points.

For example, all the different tasks are listed in a slayer points shop for a price. The amount monsters you have to kill would still be random. Tasks should cost more than you get for completing it, otherwise you could do the same tasks over and over again that you like and never run out of slayer points. So buying tasks cost around 25-50% or even 100% more than you get for completing it. At some point you'll have to 'get-task' from the slayer master again, because you will run out of slayer points finally.

Thoughts ?

EDIT: No boss tasks

As if the skill wasn't easy enough already. Also boss tasks should be excluded from this since it would just be stupid to have constant slayer helm bonuses when bossing.

Every suggestion for you looks - Stupid. Consider time you spent on commending how stupid it is - add something to it or at least Thank for suggestion and move along.
O-T: I agree, right now, SPS has utterly no more use unless you lose chaotic equipment or need more hcb.
